Quick, Simple, and Stand Behind what they sell.
Filed a claim and immediately received a response with instructions. Once I mailed the defective product, with the provided mailing label, I received my refund. Quick, simple, and honest.

Does not work well on deeper pile carpeting.
Does not have an adjustment to raise or lower the beater bar . Good on hardwood floors or tile.
